IOS中级篇 —— 字典转模型

@property (nonatomic, copy) NSString *icon;
@property (nonatomic, copy) NSString *name;

-(instancetype) initWithDic:(NSDictionary *)dic;

+(instancetype) appViewWithDic:(NSDictionary *)dic;

-(instancetype)initWithDic:(NSDictionary *)dic{

   if ([super init]) {

        _icon = dic[@"icon"];
        _name = dic[@"name"];
    }
    return self;
}

+(instancetype)appViewWithDic:(NSDictionary *)dic
{
    return [[self alloc] initWithDic:dic];

}

 

-(NSArray *)apps{
    if (!_apps) {
        NSString *path = [[NSBundle mainBundle]pathForResource:@"app.plist" ofType:nil];
        NSArray *array = [NSArray arrayWithContentsOfFile:path];
        NSMutableArray *mArray = [NSMutableArray array];
        for (NSDictionary *dic in array) {
            appViewModel *model = [appViewModel appViewWithDic:dic];
            [mArray addObject:model];
        }
        _apps = mArray;
    }
    return  _apps;

}

如果在外部用来模型来做为成员变量  一定要重新模型变量的set方法   否则没值
